If it's at or near LOW or L, add enough
coolant to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to FULL or F.
Owner Maintenance
CAUTION
Radiator coolant will damage paint.
Rinse it off quickly if spilled.
Use only soft (demineralized) water
in the coolant mixture. Water that
contains minerals will cut down on
the coolant's effectiveness.
Don't add only water. Always add a
proper coolant mixture.
The engine has aluminum parts and
must be protected by an ethylene-
glycol-based coolant to prevent
corrosion and freezing.
DO NOT USE coolants Containing
Alcohol, methanol, Borate or
Silicate.
These coolants could damage the
cooling system.
DO NOT MIX alcohol or methanol
with the coolant. This could damage
the cooling system.
Don't use a solution that contains
more than 60% antifreeze.
This would reduce effectiveness.
